Q. First vaccine of routine immunization (RI) ? 1. BCG 2. T.T. 3. OPV 4. HBV
It's TT, this reason if u know then tell me if not than search oherwise i tell u
Is it becoz mother receives tt and the child is passively immunised
Yes that's good, when mother received her first TT dose in second trimester Ig m antibody develop in mother who doesn't corss placenta barrier just because of it's larger size, then after one month when mother got TT second dose then Ig G antibody develop in mother or it's cross placenta and provide immunity to baby passivly
